HYDROGARBON-BURNER.

Specification of Letters Patent.

Application filed September 22, 1911.

Patented July 2, 1912.

Serial No. 650,837.

To all whom it may concern:

Be it known that I, FPEDRICK J. NICE, a citizen of the United States,residing at Pontiac, county of Oakland, and State of Michigan, haveinvented a certain new and useful Improvement in Hydrocarbon-Burners,and declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to hydro-carbon burners, and has for its object aburner which is controlled by a needle valve that is pushed in and outof the jet orifice.

A further object is a pair of tips of spoonli'ke shape which give theflame a more desirable spread and which can be rotated, thereby,changing the location of the spread of the flame with respect to the airnozzle.

In the drawings :F igure 1, shows an elevation of the burner. Fig. 2, isa section of the burner.

The burner consists of a tubular casing 1 which is set in a pipecoupling 2. On the inside of the casing 1 is an air nozzle 8, which issuspended in the interior of the casing 1 by the ring 3. The casing 1 isprovided with a number of air holes 1 which are disposed in a circleabout its periphery. The ring 5 may be slipped over these holes, orpartially over them, thereby controlling the supply of air at thispoint, and regulating the flame. The pipe'coupling 2 has at one side anair conduit leading into it, and through which air is passed, usuallyunder compression. This air conduit is attached to the pipe coupling bythe coupler 6 which engages in the opening of the pipe coupling 2 andover which engages the neck of the valve casing 7 into which in turnleads the air pipe 7. Within the valve casing 7 is located a valve 8,which swings on a short rod 8 that is journaled in a plate 11 heldbetween the two portions of the valve casing 7, the valve casing beingconstructed of two cylindrical pieces that are joined at their center bythe angular flanges 10, between which lies the circular plate 11. Thecircular plate 11 has an aperture which is opened and closed by thevalve 8 and the wall of this opening is oppositely beveled on theoppositesides of the rod 8 so as to form with the complementary bevelededges of the valve 8 a tight closure.

On the lower side of the pipe coupling 2 is an orifice in which isfitted the bushing 12, and through which passes the conduit 18. Thisconduit is fitted into a second pipe coupling 14 so that it may readilyturn in both the pipe coupling and the bushing. At the top of thecoupling 14 the fuel conduit 15 leads thereinto; at the bottom the draincook 16 communicates with the chamber inside, and at the rear end is anorifice which is closed by the cap 17 which is provided with a centralaperture through which slidably passes the needle valve 3 1. This needlevalve 84 is coaxial with the conduit 13 and extends from the cap 17forward to near the end of the conduit. The nozzle is formed integralwith this conduit by narrowing the inner passage of the conduit andthickening the walls. A pair of spoonshaped tips 18 and 19 are in frontof the mouth of the constricted passage 20 of the nozzle. The tip 19 isonly about half the length of its companion tip 18 and curved in towardthe center of the tip 18. The constricted passage 20 leads from the mainpassage of the conduit and is slightly inclined so as to deliver fluidflush with the surface of the smaller tip 19 by which it is thendirected into the hollow of the spoon-like tip 18. A head 21 of theneedle valve 34 engages in the constricted passage 20. A bracket 22 ishung from the pipe coupling 14, and on this bracket an arm 23 is pivotedin an oval slot 24, and upon this arm a block 25 is pivotally hung. Theblock is secured to the main end of the needle valve 34 and at its rearend has a stepped bore with the larger bore at the inside and thesmaller bore at the outside. A rod 26 has complementary portionsengaging in the stepped bore and passes through the bracket 22. The rodis provided with a handle 27 by which it may be operated and the needlevalve 34 pushed out or pulled back. A drain cock 28 is set in the wallof the pipe coupling 2 so as to drain ofl any waste products that dropinto the chamber. The ring 29 on the outside of the casing 1 intervenesbetween the flame and the air openings 1 and protects them therefrom. Ahand lever 30 is fast to the conduit 13 and may turn this conduit as itis rotatably journaled in the bushing 12 and the pipe coupling 14.

e The hydro-carbon lssuesfrom the con-' stricted passage 20 and spreadsupon the surface of the small spoon-like tip 19 by which it is spreadand guided into the hollow of the larger spoon-like tip, being dashedagainst the surface, thereby, breaking the liquid up into fineparticles. The spray is then directed by the large spoonlike tip 18angularly across the outgoing air blast 1n the air nozzle 3, whichfurther atom'izes the hydro-carbon and carries it through the mouth ofthe air-nozzle properly conditioned for burning. The direction of theflame may be varied to suit the work to be performed by turning thelever 30, which changes the location of the tips with respect to theair-nozzle.

What I claim is A. hydro-carbon burner, having in combination an airnozzle, and a fuel nozzle Within said,air nozzle, the fuel nozzlecomprising a pair of spoon-like tips one delivering fuel into the hollowof the other and the latter delivering the fuel angularly across theoutgoing air blast of the nozzle, substantially as described.

a In testimony whereof, I sign this specification in the presence of twowitnesses.
